Definitions
- the present invention relates to an odor control composition, a method of imparting an odor control property, and a treated article.
- Textile materials used in apparel tend to generate unpleasant odors due to the metabolic action of microorganisms on human sweat. This causes the breakdown of larger molecules present in sweat, which releases volatile small molecules such as isovaleric acid. Using antimicrobials sometimes is insufficient to control odors in textiles. Furthermore, current odor capturing products for textile finishing treatments are found not durable to home launderings by themselves.
- an odor control composition comprises a metal oxide and a urethane based component selected from the group consisting of a urethane based binder, a urethane precursor, and a combination thereof.
- an odor control composition comprises a blocked isocyanate binder and a metal oxide.
- a method of imparting an odor control property to a textile fabric comprises applying a composition comprised of a blocked isocyanate binder and a metal oxide to a textile fabric, and curing the composition.
- a textile fabric having an odor control property comprises a blocked isocyanate binder and a metal oxide.
- a composition comprises a metal oxide and a urethane based component selected from the group consisting of a urethane based binder, a urethane precursor, and a combination thereof.
- the composition is particularly suited for treating a textile fabric to impart an odor control property.

- Trixene is a blocked isocyanate.
- Acrygen APB is an acrylic binder.
- EDX is an instrument used to detect elemental metal on a substrate.
- An electron beam is used to bombard a target sample for analysis. When the beam of electrons hits the sample, it causes x-rays to be released from the surface of the sample that carry a unique energy signature that are specific to elements found in the sample. These x-rays are detected with the EDX detector to give elemental information about the sample and determine the presence of the element(s) in a substrate quantitatively.
- An auto regeneration test is a Gas Chromotography (GC) headspace analytical method developed for gauging the odor capturing activity of a treatment with odor capacity regenerating capability.
- GC Gas Chromotography

- the broad biocidal spectrum includes Gram-positive and Gram- negative bacteria, spore and non-spore forming bacteria, viruses, vegetative and non- vegetative fungi, yeast, protozoa, and other microorganisms.
- Biocidal activity is intended to mean an inhibiting effect on microbes. Such effects may range from cidal (killing a significant percentage of microbes within a given time period) to static (preventing proliferation, yet not necessarily killing a substantial fraction).
- weight percent Unless otherwise noted, weight percent (wt.%) is herein expressed as a percent of the total weight of the textile substrate to be treated.
